God is here.inside of me. it’s why my body works like this.
versus stupid drugs: if anyone destroys God's temple, God will destroy that person; for God's temple is sacred, &you together are that temple. (1 cor 3:17)
i don’t know about u, but I found God in science classes. no way this stuff just “happens.”
skeletal SYSTEM// starts to form at 9 weeks in belly
as adult you have “less bones” than when you were a child. b/c 350 fuse together over time to =206
skeleton weighs 18%-20% body weight (30 lbs?)
skeleton is replaced every 2 years
you’re taller in the morning because “pads” (fibrocartilage that function as a cushion/ shock absorbers) between vertebrae are expanded with no pressure on them
1/3 of your bones are tissue &live cells. the rest, ECM. (a bone exists of a osteons/“columns” &this calcium, phosphorus salts, collagen material, &a “spongy” end made for movement). this “tissue”/bone is made of a network of beams with yellow (fat storer) &red (blood formation) marrow filling in the gaps.
b/c women, not men have babies, their pelvic bones are a more rounded arch with the ability to extend more than 90 degrees, so a larger outlet exists for baby.
a baby is soft/ “cartilagey” till 18 months, having just been compressed through a birth canal (ew!)
every part is critical to the skeletal system. examples include:
scapula -irregular bone with flat thin blade; conducive to sharing a border with humerus bone
lumbar -at bottom of spinal cord, u-shaped bone is largest &ideally, strongest. (hey kim).
femur -long “spongy” ended bone, allows for much storage &support
cranial is essentially surrounded by a helmet of bone, being the most protected cavity in the body. the spinal cavity is the next most protected cavity. even when an epidural is given during labor, the doctor has to meticulously place a needle in between vertebrae to get in there.
organs protected by the bony thoracic cage include the heart &the lungs. 3 kinds of ribs: true, ”false” (cartilage), &floating (flexibility). all ribs articulate posteriorly (backside) with vertebrae &most connect anteriorly (front) to the sternum, either directly or indirectly. shape of thoracic cage is cone.
spine is “s-shaped” (&contains discs that slide) for flexibility in the trunk of your body &to absorb shock from running &jumping! “primary” curvatures refer to ones we’re born with. like the lovely lady lumps: thoracic &sacral (bum) regions. secondary ones are curvatures later developed; when baby starts to lift head (cervical) &when she starts to walk (lumbar).
muscular system is made of stripes (striation) that pull on bones/skin when contracted.
25 tons could be held by your body if every muscle was “fit.” (don’t doubt your strength).
“smooth” muscular tissue differs/is slower than cardiac &.. (intestines)
my heart &your blood// electrocardiogram, an ekg tells you exactly what you do to my <3.
p wave (1st): as a result of depolarization, atria contracts. irregular/absent waves =prob.
qrs complex (2nd/big roller coaster): contraction of vesicles, at much greater force. very deep/wide Q waves indicates heart attack. alert alert!
t wave: less “action;” ventricular muscles are relaxing &building up electrical potential for next contraction. abnormalities here may indicate calcium/potassium disturbances.
an intrinsic conduction system has an “av node” delayed for a fraction of a second to allow atria to empty &ventricles to fill before the ventricles contract again.
keratin is the waterproof protein found in skin cells
summer babies,cuidado. exposure to uv radiation makes a weaker defense (immune) system, causes wrinkles//premature aging. a breakdown of collagen/elastin fibers leads to skin cancer.
different levels of melatonin &what that looks like.. freckles are sporadic concentration of melanin. while darker skin color/Cuban -more melanocytes, melatonin producing cells
10 minutes of daily exposure to sunlight will give us the vitamin d we need for a day.
ubv radiation changes “ergosterol” in skin into vitamin d! (strengthens bones/muscles/I.S)
too much exposure can change a person’s dna! unlike plants, who only get energy from this one source, humans get energy from food &sleep. sun could add “too much energy.” spf 30 means it would take 30x more than normal amount of solar energy to burn.
i am no bird; &no net ensnares me. -charlotte bronte
"never give in, never give in, never, never, never, never -in nothing, great or small, large or petty -never give in except to convictions of honor &good sense." -w. churchill. 10/28/41

i am not afraid of storms, for i am learning how to sail my ship. -louisa may alcott
nothing in this world can take the place of persistence. talent will not: nothing is more common than unsuccessful men with talent. genius will not; unrewarded genius is almost a proverb. education will not: the world is full of educated derelicts. persistence &determination alone are omnipotent.
i am not an extraordinary man, &i am quite ordinary. but God chose me for something quite extraordinary. -a. valladares receives '16 canterbury medal.
not failure, but low aim, is crime -james russell lowell
a genuine leader is not a searcher for consensus but a molder of consensus -mlk jr.
i don't lose any sleep at night over the potential for failure. i cannot even spell the word. -"mad dog mattis"
soft minded men always fear change -mlk jr.
it is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. the credit belongs to the man who is actually in the arena, whose face is marred by dust &sweat &blood; who strives valiantly; who errs, who comes short again &again because there is no effort without error &shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worth cause; who at the best knows in the end the trump of high achievement, &who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold &timid souls who neither know victory nor defeat. -theodore roosevelt
be kind, but be fierce.-churchill
i cannot pretend to feel impartial.. -winston c.

art is the signature of man.
a dead thing can go with the stream, but only a living thing can go against it.
if you do not rise to the head not only of your profession, but of your country, it will be owing to your own laziness, slovenliness &obstinacy.
